Window replacement is one of those projects where the sticker shock isn’t really about labor — it’s the windows themselves. A single window replacement can run anywhere from a few hundred dollars to well over two thousand, and a whole-house project can swing from $6,500 to $24,000 in a typical ten-window home, depending on material and installation method. Cost scales with how many windows you’re replacing. Here’s how the pricing actually breaks down for 2026.
What Window Replacement Involves
Two decisions drive almost all of the cost variation: the window material (vinyl, wood, fiberglass, or clad-wood) and the installation method. Pocket (insert) replacement fits a new window into the existing frame and is the cheaper, faster option when the old frame is still structurally sound and not rotted. Full-frame replacement removes the old frame down to the studs and is required when there’s water damage, rot, or you’re changing the window’s size — it costs roughly twice as much but is sometimes unavoidable, especially on older homes.
Window Replacement Cost Breakdown
| Material | Installed cost per window |
|---|---|
| Vinyl | $650–$1,300 |
| Fiberglass | $850–$1,850 |
| Wood or clad-wood | $1,100–$2,400+ |
Vinyl is the budget-friendly standard for most homes and typically needs the least long-term maintenance. Fiberglass offers better durability and paintability than vinyl. Wood or clad-wood generally runs 60–130% more than vinyl for a comparable size, mostly because of the material and finish work, not the labor.
| Installation method | Installed cost per window |
|---|---|
| Pocket/insert replacement | $600–$1,000 |
| Full-frame replacement | $1,200–$2,500+ |
Pocket/insert replacement is typically 25–40% cheaper than full-frame when the existing frame doesn’t need to be touched. Full-frame replacement costs more since it involves removing exterior trim, replacing the frame, and re-flashing and re-sealing around the opening.
Labor typically makes up around 15% of the total cost per window (roughly $150 on an average job) — the window unit itself is usually 85% or more of the price, which is why material choice moves the number so much more than which contractor you hire.
| Material | Whole-house cost (10 windows) |
|---|---|
| Vinyl | $6,500–$13,000 |
| Fiberglass | $8,500–$18,500 |
| Clad-wood | $11,000–$24,000 |
Coastal markets and areas with strict energy codes or hurricane-rated glazing requirements typically run 18–48% above these national averages.
What Drives the Price Up or Down
- Frame condition. If your existing frames have rot, water damage, or are out of square, you’re locked into full-frame replacement whether you want the cheaper option or not.
- Glass package. Double-pane is standard; triple-pane, Low-E coatings, and argon gas fills all add cost but also cut energy bills — a relevant tradeoff if you’re already looking at other efficiency upgrades, like a mini-split heat pump installation, since better windows reduce the heating and cooling load a mini-split has to cover.
- Window size and type. Large picture windows, bay/bow windows, and custom shapes cost significantly more than standard double-hung or single-hung units.
- Access and floor. Second-story or hard-to-reach windows add labor time and sometimes lift or scaffolding costs.
- How many you replace at once. Contractors often discount per-window pricing on whole-house jobs versus replacing just one or two windows.
Windows are also one of the more common projects to bundle with other exterior work — if a house needs new windows, it’s often getting close to needing other exterior upgrades around the same time, whether that’s a garage door replacement or an outdoor space refresh like a new deck. Bundling quotes across projects can sometimes get you a better rate from a contractor who does multiple trades.
Estimate Your Window Replacement Cost
Use the calculator below for a rough range. This is a planning estimate, not a quote — get quotes from local contractors for accurate pricing. Nothing in those three inputs knows that two of your openings are bay windows; nothing tells it that four of them sit on a second story. How we build a range that has to live with gaps like those is set out in How We Estimate.

Practical Tips
- Get an in-person quote, not a phone estimate. Frame condition can only be assessed in person, and it’s the single biggest factor in whether you’re looking at pocket or full-frame pricing.
- Ask specifically whether the quote is pocket or full-frame. Some contractors quote pocket pricing to win the bid, then discover rot during removal and upcharge significantly — ask how change orders are handled before signing.
- Replace windows in batches if budget is tight. Doing the worst-performing windows (usually the ones facing prevailing wind or direct sun) first spreads out cost while still capturing most of the efficiency benefit.
- Check for utility rebates. Many utilities and some state programs offer rebates for ENERGY STAR-rated replacement windows, which can offset several hundred dollars of the total cost.
- Get at least three quotes. Window pricing varies significantly between contractors and brands for what’s functionally a similar product.
As always, treat these ranges as a starting point for contractor conversations, not a final number — actual costs vary by region, home condition, and the specific windows and installer you choose.
